Quantitative subchondral bone perfusion imaging in knee osteoarthritis using dynamic contrast enhanced MRI

摘要

Objective: Subchondral bone changes, characterized by increased bone turnover and vascularity, are believed to stimulate progression and pain in knee osteoarthritis (OA). The objective of this study was to evaluate the bone perfusion in knee OA using quantitative dynamic contrast enhanced MRI (DCE-MRI).
